IPC: F16H7/00
Filed: 1994-10-24
Abstract: PURPOSE: To prevent occurrence of indication and machine stoppage, which results from a decrease in durability of the film engagement width of a film dislocation preventing mechanism, by operating a film dislocation detecting means. CONSTITUTION: The traveling range of an endless film 1 on the front end side 1e is made a deep side dislocating limit position 1b on a driven roller 3 near the right end 6a beyond the right end 6b of the ring 6 from a front dislocating limit position 1a near the left end 6a of the ring 6. In a range other than this range, a film position detecting means 30 comes into action, so that indication and machine stoppage are carried out. The endless film 1 goes in a direction B beyond the right end 6b with a long-term use, however, the driven roller 3 is oscillatingly-supported at a fulcrum on the deep side (Direction B), and a bearing 7 is controlled by a balance of the pulling-down force of a tension spring 10 and a control belt 9. It is thus possible to control the endless film even if the ring is worn.

IPC: H01L21/66
Filed: 1990-10-22
Abstract: PURPOSE:To reduce the area of a resist around a hole pattern and to enable measurement of the exact dimensions of the hole pattern of the resist by disposing appropriate dummy patterns around the hole pattern to be used for dimension measurement. CONSTITUTION:A hole pattern 1 to be measured primarily, which is marked out by a chrome part 3 on a mask for which a positive-type photoresist is used, is provided in one in the central part of a measuring pattern.

Title: Current addition type digital-analog converter
Inventor: NAKAMURA YASUYUKI
IPC: H03M1/08
Filed: 1994-11-18
Abstract: PURPOSE: To reduce the occurrence of glitch and to improve the accuracy of a D/A converter by controlling the open-close operations of a 1st switch of an actuating switch circuit by a bit signal and controlling a 2nd switch by an inverted bit signal that is delayed compared with the bit signal. CONSTITUTION: The gates of a p-channel MOSFETM 51 and an n-channel MOSFETM 41 are connected to each other, and a signal S is inverted by an inverter 111 and a signal SBAR that is delayed comparing with the signal S is inputted to both gates. At the same time, the signal S is inputted to the gate of an n-channel MOSFETM 61 and this MOSFETM is turned on. On the contrary, the MOSFETM 41 is turned on by the signal SBAR when a drive circuit/D1 outputs a potential VG2OFF. Therefore, if the open-close threshold of switching transistors Q1 and Q31 are larger than the center value, the time when both switches are simultaneously turned off is reduced. Thus the occurrence of glitch is also reduced.

Title: Rotary magnetic head device
Inventor: TERAYAMA SOUJIROU
IPC: G11B5/02
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To reduce cost for parts and assemblage and also to reduce occurrence of noise by directly connecting each coil of a stator substrate of a rotary transformer to an equipment chassis via a connector pin provided on this chassis. SOLUTION: Since a signal between the equipment chassis 16 and the rotary transformer 15 is inputted and outputted via the connector pin 18 erected on the equipment chassis 16, the equipment chassis 16 and the rotary transformer 15 are directly connected up by the connector pin 18. Consequently, the number of parts is reduced and the assemblage is easily performed. Moreover, since the coil on the stator side, disposed on the stator substrate 15b of the rotary transformer 15 is directly taken out to the side of the equipment chassis 16 via a stator land and the connector pin 18, the occurrence of noise is eliminated even in a comparatively weak RF signal from a magnetic head 17 at the reproducing time.

Filed: 1988-11-11
Abstract: PURPOSE:To easily remove the pigment particles depositing and remaining on the region except on a specified pattern in the development by bringing a sticky material into contact with the glass substrate surface on which a resist film is deposited. CONSTITUTION:A black matrix 1 formed on the glass substrate 2 is not dissolved in the development, contains a resinous component, and sticks firmly to the substrate 2.
